SOFT-TREAD RACING-SHOE.

SPECIFICATION forming part of Letters Patent No. 585,202, dated J' une 29, 1897. Application led DecemberSO, 1896. Serial No. 617,436. (No model.)

To @ZZ whom t may concern:

Be it known that I, FREDERICK W. HAHN, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful Improvement in Soft-Tread Race-Horseshoes, of which the following is a specification.

The object of this invention is to produce a light soft-tread horseshoe.

The invention consists in forming a fret- Work base in a channel for supporting an elastic packing in a horseshoe-frame and a wire screen to prevent the packing from coming in contact with the hoof.

Figure l represents the shoe having part of the elastic packing removed. Fig. 2 represents two forms of fretwork in the channel. Fig. 3 represents the cross-section of Fig. 4 represents the cross-section of Fig. l on line x x. Fig. 5 represents Fig. l on line Qc' 0c. Fig. 6 represents Fig. 2 on line Q53 m3, and Fig. 7 represents Fig. l on line 004 m4.

A in the several figures represents a horseshoe-frame cast from malleable iron or struck up, having nail-flanges A, nail-holes A2, and

`calk A3.

A4 are right-angle flan ges ormin g the eXterior Wall of the channel A7, as shown in Figs. l, 2, and 7, and these iianges merge into the large calk A3 at the front of the shoe.

A5 is a right-angle flange forming theinterior wall of the channel A7, as shown in Figs.

:l and 7. This flange is provided with elevations AG, which are bent over onto the packing D to hold it in place, as shown in Figs. 1, 3, and 5. That the packing D may not get loose in the groove A7 the calk A3 is provided with fingers B, which extend below the calk, as shown by dotted lines B, Fig. 5, and is separated from the calk above its tread-surface by the groove B2, as shown in Figs. l and 5. By this plan the finger B will not wear oft at its base when bent over, as shown at B', Fig. l.

The shoe in Fig. 2 shows two channels A7 formed on the sides of the shoes, leaving a space back of the calk A3. By this plan the shoe is made lighter, as only a thin web E unites the calk A3 and the iiange A5, and in order that more strength may be given to the web E and front part of the shoe the vertical iange A5 is united to and extended across the rear of the web E.

The calk A3, Fig. 4, has its tread-surface A8 tapered back that a sharp edge may be formed on its front edge. l

The narrow slots C through the base ot' the channel A7, Figs. l, 4, 6, and 7, are for the purpose of making the shoe lighter. They are formed with tapering walls, as shown at C in cross-,sections Figs. 4, 6, and 7 which prevents the packing D from coming in contact with the horses hoots and causing the animal to become lame. These-slots C are cast diagonally across the channel, which prevents the shoe from breaking as it is spread or contracted in iittin g the shoes to the horses feet.

The holes C and C3, Fig. 2, are modifications of the slots C, the holes C3 being made very fine, While C are large, but are provided With a wire-netting G, Figs. 2 and 6, which prevents the elastic packing from reaching the hoof.

That the shoe may be still further reduced in weight I form recesses G2 in the web E. (See Fig. 2.)

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of. the United States, is-

l. Al1orseshoe-framehavingslots C,langes A4 and A5 forming a channel A7, in combination with the Wire screen G located in the base of the channel A7, and the elastic packing D, as and for the purpose described.

2. A horseshoe-frame having slots C or holes C', a channel A7 formed by the flanges A5 and A4, the said iange A5 having elevations A6, in combination with the wire screen Gr located in the base of the channel A7, and the elastic pack-ing D, as and for the purpose described.

In testimony that I claim the foregoing as my invention I have signed'my name, in presence of two witnesses, this 23d day of December, 1896. Y

FREDERICK W. HAHN.
